TFIIH

TFIIH is a crucial protein complex involved in gene expression and DNA repair. It functions as a multifunctional enzyme with roles in initiating the process of copying genetic information into RNA (transcription) and fixing damaged DNA. TFIIH contains enzymes that unwind DNA strands, allowing other molecules to access the genetic code. It also helps signal and coordinate repair mechanisms when DNA is broken or damaged, maintaining genetic stability. Overall, TFIIH ensures that cells accurately read and maintain their DNA, supporting normal cellular function and preventing genetic disorders.
